To all whom it may concern:

Be it known that I Ansnn'r ENNIS Han- :osnsoN, a subject oi the King 'of Great Britain, residing in Toronto, Province of On- 5 tario, in the Dominion of Canada, have invented new and useful Improvements in Tubes for Pneumatic Tires, of which the following is a specification.

My invention relates to improvements in 10 inner tubes in which the tube is provided with means to'prevent the pinchin of the tube b the head of the casing in that portion the tube adjacentto the rim of the wheel. In my co-pending application I have shown protecting fabricarranged in strips longitudinally around the rim side of the tube overlapping longitudinally and transversely.

The objects of my present improvements First. To provide. a tube which carries on or imbedded in its rim side the means whereby it is protected from pinch or in- Second. To arrange the protection in each manner as to permit longitudinal, transverse and diagonal expansion of the protected side of the tube.-

Third. To arrange the protecting strips n such manner as to provide a number of openings which would be suitable for be ing apertured to receive the valve stem.

Fourth. To uniformly imbed the said prggecting means in the rim side of the tu protection which will be adapted to co-operate with any protected and thickened tread designed to overcome the effect of punctures in the tread side of thetube.

I attain these objects by the mechanism illustrated in the accompanying drawings.

Fig. 1 is a plan view showing a section of the tube with my improved device applied.

Fig. 2 is a transverse section of the-tube as shown in Fig. 1, through the line Fig. 3 is a plan view of a portion of the tube showing the addition of an extra piece of valve base fabric.

Fig. 4 is a modified-plan view showing the relation of the protecting fabric at the ends of the tube.

Fig. 5 is a lau view showing the-relation of the f ric in the rim side of the tube to that in the tread portion.

til:

Fifth. To provide a suitable rim side Fig. 6 is a cross section of Fig. 5 show the transverse relation of the parts. I

Similar reference characters refer to similar parts throughout the several views. In Fig. 1 I have shown a section of the tube 7 showing in elevation in its central portion 8 the relation of the strips 9 and 9 in dotted line formation with the valve stem 10 having the button 1L and the reduced portion 12 in position to be inserted from without in the hole 14. I also show 1n similar relation to the diagonal strips the hole 14', which might also be punched" for the reception of the valve stem. 1 have shown a portion of the rubber of the tube broken away at 15 showing in plan view the strips 9 separated by the rubber of the tube 16 and the relationvof the strips 9 shown in dotted lines. On the reverse end of the tube 1 have shown the rubber of the tube cut away at 17 showing a portion of the fabric strips 9, and again cut away at 18, showing the pesition of the fabric strips 9' with the separating strips of rubber 19. in Fig. 2 are shown the strips 9 and ii in their transverse relation to each other in the line AB of Fig. i. a

In Fig. 3 is shown a section of the tube in which the rubber is cut away at 20, showing the additional fabric base piece 21 having the slot 22, superimposed upon the diagonally arranged strips 9 and 9', the central point of the slot 22 being superimposed above the point of intersection of the spaces between the strips 9 and 9', as shown in Fig. l, at the point 14'. The rubber oi the tube is further -broken away at 23,

showing the strips 24, which correspond to the strips 9 in Fig. 1 in their relation in the tube; the said strips 24 and the rubber are further broken away at 25, showing the ofrubber 26 separating the strips 24: from the strips 2% which are shown in elevation together with the separating rubber 27,

which separates. the individual sections of the series 24' from each other diagonally.

The strips 24 and the rubber 28 of the tube are further broken away at the right showing the relation of the strips 24. to the in-' terior surface of the tube.

In Fig. 4 I show sections of the tube 7" having oartsbroken awa at 29, 30 and 31, showin the relation of t e fabric strips in the be y of the tube, while at the end 32 I m show. the fabric strips 9 and 9' projectin and adapted to overlap with the. strips and 9' which are shown exposed at 33 and 34, when the ends of the tube are joined together. The tube is broken at 35.

In Fig. I have shown a section of the tube 7" showing in elevation the rim side fabric strips 9 and 9' in relation to each other. I have broken away a portion of the tube at 36 showing in plan view the tread portion of the tube in which the thickened rubber portion 37 is broken away showing the fabric strips 38 and 88' separated longitudinall by the rubber 39 and broken transverse y at 40 and 40'. The strips 38 and 38 and the rubber of the tube are broken away at 41, showing the strips 42,

. s2 and d2" imbedded in the rubber of the tube and separated by the fihn of rubber 41 from the strips 38 and 38', the said strips 42, 42' and 42 being separated from each other longitudinally by the strips of rubber tection app ied on the rim side of the tube designed to yield longitudinally, transversely and diagonally, and providing an elastic relation between the fabric and the rubber of the tube, the fabric being uniformly distributed in the necessary portion of the rim side of the tube in orderto protect the same from pinches by the bead of the shoe or from injur through carelessness in placing the tube 1n position. I have also shown the same to be provided with a plurality of formations suitable for providmg an aperture for the reception of the valve base, while the fabric is so arranged as to distribute the elasticity uniformly throu bout the length of the tube after the same as been joined together.
